Hi, I'm a complete newbie and we set our 65 litre (around 17 US gallons) tank up on Friday. Filled with water, switched on filter, heater, light and air stone, treated with aqua safe. I've been adding 2 to 3 fish flakes on a daily basis. The ammonia levels are low, colour looks inbetween 0 and 0.25, nitrates are 0. Is that normal or should ammonia be higher by now? Filter etc is all still switched on, temp of tank is 30 degrees celsius. Am I doing anything wrong or have I missed anything out?
